6. 個人經驗與觀點
「有次我要將 10 張對話截圖拼成一張長圖 Send 俾客，用電話 App 拼完壓縮到濛晒，用 Photoshop 又要等佢慢慢 load。後來我用呢個工具，30 秒就搞掂，仲要清晰過我用電話拼嗰啲。拼圖唔係技術問題，係 排列嘅美學——點樣排、留幾多白位、用咩底色，都影響人哋點樣睇你嘅內容。垂直拼適合講故仔，水平拼適合做對比。揀方向之前，諗吓你想表達咩。呢個工具嘅好處係：你唔使等 Photoshop 開機，你只需要 幾秒鐘試到啱為止。」

6. Personal Insights & Expert Advice
"I once needed to stitch 10 chat screenshots into one long image for a client. Phone apps compressed it to blur, and Photoshop took forever to load. This tool did it in 30 seconds, and the quality was better than anything my phone could produce. Stitching isn't a technical skill—it's about how you arrange things. Vertical tells a story (top to bottom). Horizontal makes comparisons (left to right). Think about your message before choosing a direction. The beauty of this tool: no Photoshop loading time—just a few seconds to get it right."
